I love poppers and am a gay guy so no idea what it does for women. Its a vasodilator and it relaxes smooth muscle, makes anal sex much easier. The high is short lived but good, also, for me, it relieves pain, or makes me horny so I dont notice it as much. I am a total popper whore and use it too much, some brands do give a headache, you just need to try different ones out to see what suits. As others have pointed out they do drop blood pressure, so if your on antihypertensive (BP drugs) give it a miss. Saying that I do use them with viagra and meth and havent had any problems....yet. It is risky though.
good luck and happy experimenting.
